One accepting a std::string and one accepting a std::wstring. In g++ version 10.3.0-11 on sh4 only the std::wstring version is available, so when it tries to compile code that uses the std::string version it fails. The problem is that for some reason the the file /usr/include/sh4-linux-gnu/c++/10/bits/c++config.h provided by libstdc++-10-dev_10.3.0-11_sh4.deb contains the line /* #undef _GLIBCXX11_USE_C99_STDLIB */ The corresponding file for other architectures contains #define _GLIBCXX11_USE_C99_STDLIB 1 This is a regression wrt earlier versions, since this used to work without problems.
